Abstract
This study examines the effect of Herding in different states (low, high and extreme volatility) in Tehran Stock Exchange during the years 2009-2013 using Chang et al (2000) and Balcilar et al (2013) models. In this survey herding are tested under 3 market regimes in selected industries: Cement, Chemical, Pharmaceutical and Investment.
The results don't show evidence of herding in 4 industries using static model (Chang et al, 2000). So dynamic model (Balcilar et al, 2013) was used to analyze Herding under 3 regimes in which our results support the presence of herding under 2 market regimes (high and extreme) . The results also demonstrate evidence of herding behavior under the high volatility regime for all of the selected industries. Herding under the extreme volatility regime is only found in investment and cement industries.

Abstract
The main objective of this paper is to investigate the impact of corruption on the military burden of developing countries during the 2000-2015 period. To achieve this goal, a general model of military expenditures , two indexes of corruption including corruption perceptions and control of corruption, Panel Co-integration analysis and two-stage system generalized method of moment estimator (SGMM), has been used. The results of the estimation of the research model show that the effect of corruption on the military burden of the studied countries is positive and significant. According to other results, civilian spending (as an opportunity cost of military spending) and democracy have had a negative and significant impact on the military burden of developing countries. . Population as a social variable has a positive and significant effect on the military burden of developing countries, which indicates that defense is a public good. Per capita income and lagged military expenditure also have a positive and significant effect on the military burden of the studied countries. The average military burden of the countries of the world has also had a positive and significant impact on the military burden of developing countries, which indicates a rivalry of arms.

Abstract
Banking system is one the important sectors of economy and as vital institution of money market, plays a very significant role. Also, due to the nature of the banking system performance, the activities of banks have a close relationship with the exchange rate changes. This paper tries to assess the effects of exchange rate variations on macroeconomic variables via the banking system using a macro-econometric model and approach of bounding ARDL during 1973-2017. The results indicated that an increase in the exchange rate through non-performance loans and long-term deposits will led to decreased credit providing by the banking system. On the other hand, an increase in the exchange rate through the net open position and banks’ capital account had a positive impact on banks’ credit provision. However, the negative impact of a change in the non-performance loans and long-term deposits is stronger than the positive impact of the net open position. In addition, the decreasing trend of providing credit by banking system had a negative effect on investment. Finally, an increase in the exchange rate causes a decrease in the long-term deposits and the money multiplier which has a negative effect on liquidity and price level. An increase in the exchange rate through the capacity utilitization rate had a negative impact on GDP. Also an increase in the exchange rate led to increased liquidity and price level.
